FAG bearing disassembly and maintenance methods

First put FAG bearing in gasoline cleaning, wipe the residues of sludge and dust on the bearing, bearing all rusty wipe gently with the metallographic sandpaper polished, until no fingered rough feel. After the second use dry cloth to clean the bearing wiped dry, soaked in the anti-rust oil again. In the process, you would have a FAG bearings completely and rust-proof oil contact, don't stop rotating bearing, so that the rust-proof oil forming oil film covering on the surface of bearing, achieve the goal of rust. The third step with lithium base grease or with butter, evenly coated on the surface of FAG bearings, including inside and outside the circle, wheels, cage. And wipe while rotating bearing, makes the butter into the real bearing internal, sufficient lubrication effect. The fourth step is the last line of packaging process is. In order to save costs, we 'waste', scrapping of cement bags in the warehouse, the packing bag of cut into appropriate size, would FAG bearing good tight, package, label after good FAG bearing specifications back on the store shelves. FAG bearings remove and install the same carefully. Careful not to damage the bearing and the parts, especially interference fit the bearing down, and the operation is difficult. So, in the design stage to consider in advance to facilitate disassembly, designed and manufactured according to need remove the tools is also very important. During disassembly, removal methods, according to drawing order, cooperation condition investigation FAG bearing, foolproof for disassembly operations. 1, the outer ring of the removal of removal of interference fit of the outer ring, beforehand in setting several outer shell on the circumference of a circle of extrusion screw with screws, one side equal to tighten the screw, remove. The screw hole cover usual blind plug, the separation of tapered roller bearing type bearing, shoulders set several incisions in the shell, using block, remove by press, or tap the disassembly. 2, remove the inner ring of the remove of cylindrical hole bearing, can use simple mechanical pull out the latest pressure. At this time, must pay attention to the inner ring under the pulling force. Large FAG bearing inner ring remove oil pressure method is used. By setting on the axis of hydraulic oil hole, in order to make easy to pull out. Width of the bearing is oil pressure method and drawing fixture and disassembly operations. NU, NJ cylindrical roller bearing inner ring remove can take advantage of the induction heating method. In a short time heating the local, make the inner ring expansion after drawing method. 3, remove the removal of relatively small band of taper hole bearing sleeve bearing, with fastening on the shaft gear support inner ring, the nuts back a few times, use the block with a hammer beating the disassembly. Large FAG bearing, using the hydraulic remove easier, in the oil hole on the shaft taper hole pressure oil, make the inner ring expansion, remove the bearing method. Operation, has a bearing may suddenly emerge, it is best to nut used as gear block as well. First put FAG bearing in gasoline cleaning, wipe the residues of sludge and dust on the bearing, bearing all rusty wipe gently with the metallographic sandpaper polished, until no fingered rough feel.
